Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability in SMA100 allows a remote authenticated attacker with SSLVPN user privileges to bypass the path traversal checks and delete an arbitrary file potentially resulting in a reboot to factory default settings.
